-, RAIL :BnAoE Application filed November '7,

To all whom 'it my concern: Be it known that 1, WILLIAM E. DUNN, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York,have invented certain new and useful Improvements in Rail Braces or Clamps; and I do declare the following'to be a full, clear, and exact description of the invention, and such as will enable others'skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification. Y i The particular object of the present invention is to provide means for preventing the spreading or lateral displacement of the rails and insure the maintenance Figure 1 is'a plan view illustrating one form of rny' improved clamp which is designed to be applied to the:

rails after they have been put in place. Fig. 2'is a 1' side elevation of the same. Fig. 3 is a modified form designed'tobe applied to new rails as they are being laid. Fig. 4 isaside elevation thereofl Referring to Fig. 1 which shows the clamp in two positions, the initial position being indicated in dotted lines and its positive gripping position being indicated in full. I

The ties are indicated at 1, the which are of usual construction: I 3 .i11dicates the clamping bar having end jaws or clamping portions 4 formed integral therewith and adapted to fit under the base of the rail andpver the outside rail flange so that the tongue of the; jaw when forced to proper position will bear upon theweb. of the rail. Spikes 5 are driven through suitable holes provided in the clamping bar 3' into the ti e 1, to rigidly hold the bar in gripping'position. After the clamping bar has been forced to position Iemployspikes 5 sta g gered in the usual manner to increaii rails. .1. k

f Itiwill be seen that the clamping bar 3 illustrated in Fig. l is made longer thaii that shown in Fig. 3, its

The clamps maybe formed some with jaws at reso that the clamps instead of being parallel when in position, will be at an brace one another. I

It will be seen that by the use of my invention, the spikes are relieved of the outward pressure of the rails caused by the lateral or swinging motion of the cars,

and consequently the necessity of drawing and redriv the spikes to keep the which is at present frequently required is eliminated.
